Mpirun opens separate shell on each machine/node, so the "ulimit" will
not be available in new sheel. I think if you will add "ulimit -c
unlimited" to you default shell configuration file (~/.bashrc in BASH
case ant ~/.tcshrc in TCSH/CSH case) you will find your core files :)

I set bash to have unlimited size core files like this:
$ ulimit -c unlimited
But, it was not dropping core files for some reason when I was running with
mpirun. Just to make sure it would do what I expected, I wrote a little C
program that was kind of like this
int ptr = 4;
fprintf(stderr,"bad! %s\n", (char*)ptr);
That would give a segmentation fault. It dropped a core file like you would
expect. Am I missing something?

Some process is exiting on a segv -- are you getting any corefiles?
If not, can you increase your coredumpsize to unlimited? This should
let you get a corefile; can you send the backtrace from that corefile?

Subject: [OMPI users] job running question
We are trying to build a new cluster running OpenMPI. We
were previous
running LAM-MPI. To run jobs we would do the following:
$ lamboot lam-host-file
$ mpirun C program
I am not sure if this works more or less the same way with
ompi. We were
trying to run it like this:
$ [james.parker@Cent01 FORTRAN]$ mpirun --np 2 f_5x5 localhost
mpirun noticed that job rank 1 with PID 0 on node "localhost"
exited on
signal 11.
[Cent01.brooks.afmc.ds.af.mil:16124] ERROR: A daemon on node localhost
failed to start as expected.
[Cent01.brooks.afmc.ds.af.mil:16124] ERROR: There may be more
